    1. Temperate forests
    2. Tropical rain forests
    3. Savannah
    4. Scrub land
Correct Option: B

The term “coral reef” generally refers to a marine ecosystem in which the main organisms are corals that house algal symbionts within their tissues. These ecosystems require: 1) fully marine waters; 2) warm temperatures; and 3) ample sunlight. They are therefore restricted to shallow waters of tropical and subtropical regions.
